Abstract

A split recoating mold for use in recoating optical waveguide fibers with a UV-curable resin is provided wherein: (1) the mold, when closed, forms a cavity for receiving the portion of the fiber which is to be recoated, the cross-sectional size and shape of the cavity being essentially equal to the cross-sectional size and shape of the original fiber (2) the mold includes an injection port for introducing a UV-curable resin into the cavity and (3) the mold includes means for introducing ultraviolet light into the cavity so that resin located in regions of the cavity remote from the injection port will cure prior to resin located in regions of the cavity near the injection port.
